Jared for me I never match up to the 300 series line just for the fact that I can't get the ball to do what I want. The 300T is really good on medium to medium dry fresh lanes. Once they start to hook the 300T wants to read too early. You can shine it to help get the ball to retain more energy. But honestly if the 503C is too much, the only option really is to get a 300 series ball or drill the 508A really weak.
